Efficacy of farmyard manure for growth and yield of onion (Allium cepa L.) cv. N-53

Abstract

Increasing population trend demands higher production per land to sustain human life. Green revolution is old story now and inorganic fertilizer input proven harmful in long-term impacts. Though organic farming has its long term affect in improving soil quality along with production. Present study was carried out to evaluate the response of Farm yard manure for onion cultivation and production. Different treatments were decided on the basis of nitrogen requirement by the onion crop with zero manure and 100% NPK check. Statistical analysis suggests significant (F-test at 1% & 5%) increase with increase in dose with max number of leaves (11.85), fresh weight of bulb (116.7g), with average diameter of bulb (5.6cm) suggested 0.04%, 0.46% and. 05% increase when compare to NPK production. Further reported increase in some biochemical along with bulb sulphur (5.40 ppm) without affecting soil quality.
